Abstract (en)
[origin: WO2013054085A1] A generating apparatus (10) for generating electrical power from a horizontal water flow, for example tidal flow or river flow, comprises a fixed hub (32) on a support structure (12) and a power wheel (34) arranged for rotation about a vertical axis about the hub (32). The power wheel (34) is provided with rotor vanes (36). One or more generators (30) are provided on the hub (32) to produce electrical power output. A shroud (60) is rotationally mounted on the hub (32) and arranged to cover at least some of the rotor vanes (36) of the power wheel (34). A directional controller (74) holds the shroud in a predetermined rotational position relative to the hub (32) dependent on the direction of the water flow. The hub (32) and the power wheel (34) may have controlled buoyancy so that they can be positioned in the strongest current or flow.
